Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

With this experiment, the experimenter wish to create a new model of itch based on the substance BAM8-22 (Bovine Adrenal Medulla), which is found naturally in the human body and which has proved to evoke itch.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

With this experiment, the experimenter wish to create a new model of itch based on the substance BAM8-22 (Bovine Adrenal Medulla), which is found naturally in the human body and which has proved to evoke itch.To explore and validate the dose-response features of a of this new itch model based on BAM8-22.

The experimenter will also characterize the sensory quality and temporary aspects of BAM8-22 skin prick test (SPT) in comparison to the inactivated-cowhage delivery system.
